Q: Are sintered brick concrete bricks?
Sintered brick: brick made of clay, shale, coal gangue or fly ash, made by molding and roasting at high temperature. Bricks used for masonry, load-bearing and non load bearing walls are collectively called sintered bricks.According to the raw materials, they are divided into sintered clay brick, sintered fly ash brick, sintered coal brick and so on.A sintered brick with a solid or void ratio of less than 25% is called a sintered ordinary brick.The production and use of ordinary clay brick has been in China for more than 3000 years. Nowadays, ordinary clay bricks still dominate the wall materials used in construction projects. Although the ordinary clay brick has many disadvantages, due to its low cost, simple process, design and construction technology is mature and people's inertia and other reasons, the ordinary clay brick for quite a long period of time, especially in rural areas, is still one of the main wall materials.
Q: What is refractory brick? What is refractory clay? ?
refractory brick----is refractory material with a certain shape and size. According to the preparation process, bricks can be classified into burnt bricks, unburned brick, electric melting brick (fused cast brick) and the refractory insulating bricks; according to the shape and size, bricks can be classified into standard brick, ordinary brick and specific brick and etc. High-temperatured building material and structural material that can be used to build furnaces and various thermal equipments, and can endure various physical and chemical changes and mechanical effects at high temperature. For example, refractory clay brick, high alumina brick, cilica brick and magnesia brick and etc.. Fireclay -- usually refers to a kind of soil clay used for fire the stove and the furnace hearth in folk 1, characteristics and usages: Clay refractory brick is a kind of weak acid refractory material, its thermal stability is good, suitable for hot blast stove, various boiler lining, and flue, smoke room, etc.. 2, product specifications: Standard form, general profile, special shaped and special shaped brick. Physical and chemical properties of clay refractory bricks. The upper limit ---- about 1500 degrees under normal pressure
Q: How are shale porous bricks and clay porous bricks distinguished?
Weathering resistance is better than clay brickDue to differences in clay shale and its performance, the national standard requires shale weathering properties than clay bricks.
Q: What is the refractory brick in silicious model?
Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
Q: Is the waste of the fire resistant hazardous waste?
it mainly depends on whether the refractory bricks contain chromium, if not, we only need to properly dispose of them, it would cost less and assure that there is no bad effect on people and the environment, shoot two hawks with one arrow; if there is hazardous elements like chromium and mercury, it may cost much and be disposed as industrial waste(or construction waste) by local environmental protection department, it is ok if there is a large amount of waste, because the environmental protection department will not take those waste that is not obviously dangerous seriously, even if it is dangerous waste. If there is no suitable manufacturers. It is better to look for a refractory brick manufacturers to recycle it, the cost is acceptable if the amount is small. In general, these heavy metal containing refractory bricks need to be disposed by the company that has quality to dispose such hazardous waste.
Q: 90 porous brick and ordinary shale brick, clay brick difference
Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
Q: th choose of different refractory bricks in the rotary?kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
Q: The shape and size of general used refractory brick
240mm * 115mm * 53mm. and the width is 115mm, the shape and size of mechanism red brick is: 230mm * 114mm * 65mm, the outline dimension of special refractory brick is of 65mm thickness according to the national standard: Length is 230mm. That is: Length is 240mm. General type refractory brick's outline dimension is of 114mm width. That is, thickness is 53mm: 345*328*97
Q: Can mud and salt be used as refractory materials
Clay can be used as a refractory material, but salt can certainly not be used.
Q: What are the differences and uses of non clay bricks, non clay bricks and ordinary red bricks?
Non clay brick clay brick walls can be completed, insulation and so on, often also can have some characteristics, such as light weight, heat insulation, heat absorbing ability better and so on.
